湖南省是我国柑桔主要产区之一。近年来,柑桔全爪螨[Panonychus citri(McGregor)]的抗药性和再增猖獗成为柑桔生产上的一大难题。国内外相继开展了利用植绥螨控制叶螨的研究和实践,证明植绥螨是自然界控制叶螨种群的有效生物因子。我们从1985年开始,对湖南省植绥螨资源进行了调查,从中发现江原钝绥螨(Amblyseius eharai Amitai et Swirski)是我省分布普遍的一个种,其捕食习性和捕食量均优于其他种类。为此,1986～1987年,我们对江原钝绥螨的生物学及其对柑桔全爪螨的捕食作用进行了研究,为今后开展柑桔全爪螨的生物防治提供依据。
Hunan Province is one of the major citrus producing areas in China. In recent years, the resistance and rejuvenation of Panonychus citri (McGregor) have become a major challenge in citrus production. At home and abroad have carried out the use of phytoseiidae control spider mite research and practice that phytosesthetic mites is the natural control of spider mite population effective biological factors. Since 1985, we investigated the phytoseiose mite resources in Hunan Province and found that Amblyseius eharai Amitai et Swirski is a species widely distributed in our province, and its predation habits and predation rate are superior to those of other species . For this reason, from 1986 to 1987, we studied the biology of Amblyseius amblyseius and its predation on Citrus grandis mites, and provided the basis for the future biological control of Citrus grandis.
